IMPROVEMENT IN VAPOR-BURNERS.

Speciication formingpart of Letters Patent No. 124,151, dated February 27, 1872.

Specification describing an Improved Vapor- Burner, invented by ROBERT W. PARK, ot' Philadelphia, county of Philadelphia, and State ot' Pennsylvania. Y

My invention consists of certain improvements in vapor-burners, too fully explained hereafter to need preliminary description, the said improvement being directed to the ei'ective vaporizing ofthe hydrocarbon from which the ignitible gas is genera-ted.

In the accompanying drawing, Figure l is an external view of myimproved vapor-burner; Fig. 2, a vertical section of the same; and Fig. 3, a transverse section on the line l 2, Fig. l.

The tubular body A of the burner has at its lower end the usual pointed screw-valve B and seat a', which terminates at its upper end in a small aperture for the escape of the oil or vapor into the mixing-chamber b, the latter occupying the greater portion of the interior ot' the body ot' the burner, which is supplied with air at the bottom through openings c c, and has at its upper end a tip, I), similar to that ot' an ordinary gas-burner. The supplypipe F communicates, as usual, with an elevated reservoir containing a supply or light hydrocarbon, and is, in the present instance, at right angles to the body ofthe burner, and is secured to the sa me at a point considerably above the lower end of the mixing-chamber b. An inclined tube or passage, G, forms a communication between the supply-pipe and body of the burner beneath the valve-seat, and I prefer, in order that this passage be continually heated, that it should be as close as possible to, and be cast in one piece with, the body of the burner and with the supply-branch, as shown in the drawing. It will be evident, however, that the supply-pipe could be brought close. up to the body ofthe burner and be then bent downward to form the passa-ge G, in which case the latter would be screwed into or brazed to the body of the burner below the scat of the valve. There is an aperture, d, in the side of the mixing-chamber b, an independent jet of ignited gas from which is caused to play upon a wing, H. In the present instance, however, this wing is a continuation of a tongue, h, which extends down into the passage G almost to the bottom of the saine, and is maintained at a temperature almost as high as that of the wing, the consequence of which is the rapid vaporizin g ofthe hydrocarbon, which, in a thin film, is caused to pass around and in contact wi-th the said tongue in its downward passage through the tube G. The wing, with its tongue h, may be simply driven tightly into the opening formed for it in the top of the supply-pipe, or it may be brazed or otherwise permanently secured to the latter. Another important feature of my invention is the hood or'shield K, which extends around the wing H, and overlaps the body ofthe burner to a slight extent. This hood prevents draughts ot' cold air from striking the wing, retains a volume of heated air around the latter, and consequently causes -the said wing and its tongue h to be maintained at a. higher temperature than if the said wing were exposed as usual. The hood is in the present instance secured to the burner by a sleeve, K1, which extends around the supplypipe. This sleeve, however, is not essential as a means of supporting the hood, butit serves the more important purpose ot'conductiu g heat from the hood to the supply-pipe which it embraces, and of thus partially vaporizing the oil before it enters the tube or passage G. The sleeve K1 embracing the supply-pipe maybe used in connection with any metal object heated by the tlame from the oriice cl. There is also a tail-piece, K2, projecting downward from the sleeve K1, and partly embracing the tube G, for the purpose of still further heating the latter and ot' thus insuring a thorough vapor-ization of the oil.

I claim as my invention- 1. The combination, in a burner, of the tip D, the opening d, through which issues a supplemental jet of gas, and a plate heated by the said jet, and having a tongue extending into the supply-pipe, as set forth.

2. The combination, substantially as described, of a hood or shield, K, with the heating plate or wing H.

The combination, as set forth, ofthe ring and tongue I-I h, heated by a. supplemental iiame, the shield K, and the sleeve K1 encircling the supply-pipe.

4. The combination of the hood K, heatingplate II, sleeve K1, tube or passage G, and tail-piece K2 projecting from the said sleeve, all substantially as specified.

In testimony whereof I have signed my name to this speciiication in the presence of two subscribing witnesses. y
